The Fial answer on V4\no solder DVD media

Please anybody do me a favor and try to clarify once and for all exactly what media will work on a PS2 Ver. 4 with no solder mod and swap magic 2.0 discs. I have read and been told varying answers.DVD-R,DVD+R,DVD+RW which one. I am becoming hesitant on buying a burner, media, etc...
All help is greatly appreciated. Also what would be a good burner to purchase. The cendyne 4x DVD-R looks good!
